||Recombinant Human IFNB1 (NP_002167.1) (Met 1-Asn 187), fused with no tag, was produced in CHO Cells.
||Lyophilized from sterile 20mM HEPES, 150mM NaCl, pH 7.2
||The recombinant human IFNβ consists of 166 amino acids and has a predicted molecular mass of 20 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh IFNβis approximately 22-24 kDa.
||< 1.0 eu per μg of the protein as determined by the LAL method.
||Samples are stable for up to twelve months from date of receipt at -70oC.
||Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
||It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4oC before opening to recover the entire contents.
